this is a good question. From a practical point of view 4000 meters might be a good max value.
what I found out when I did tests with terrain and height map of vanilla daggerfall is that it uses exponential scale for heights (see this thread: viewtopic.php?f=14&t=10
). But I would not go for this in daggerfall unity tbh.
Ah yes, that thread is what got me curious, great read
It would be a lot of work to create new map with more detail, it's a shame we don't have access to the source material. Something tells me there was more detail to the entire thing than they were able to implement.
If what you mean by "what it should be" is what vanilla Daggerfall is like, then about 100-150m. But no one wants that, so I would say whatever looks reasonable basically (I can't think of any numbers myself, but I would just go by Nystuls).
Yeah, same as with Morrowind (Red Mountain being no higher than 270 meters) and in Daggerfall it's even worse because of the scale being rendered. That's why I cranked up the vertical scale to 4096 in L3DT. I wonder what height the Wrothgarian Mountains should be in theory seeing that the land is actually true to scale compared to the later titles. Re-creating a map for Daggerfall would leave one with a lot of artistic freedom as long as you took the regions into account.
Not saying that you guys should do this btw, you have more than enough to do as it is. I'm just musing , I imagine when the engine is completed, it should be possible to plug in new terrain like Nystuls is already doing in a way.
